Remove show/hide API

This CL removes the show/hide API from MediaControlView2 and instead
provides the developer with the same function by calling
setVisibility(View.VISIBLE | View.GONE), and calling the new APIs
set/getTimeout() and requestPlayButtonFocus(). The original Runnable
code has been moved to onVisibilityAggregated() as per API council's
request.

+ * In addition, the following customizations are supported:
+ * 1. Modify default timeout value of 2 seconds by calling setTimeout(long).
+ * 2. Set focus to the play/pause button by calling requestPlayButtonFocus().
